Stochastic Differential Game-Based Malware Propagation in Edge Computing-Based IoT

Algorithm 1

The stochastic game algorithm for the defenders and attackers (the optimal strategies for the defenders and attackers).

	Input: ;
	Output: optimal state trajectory and optimal strategies ;
(1)	Initialize game parameters , and ;
(2)	Set the rate parameters ;
(3)	For  = 0 to ;
(4)	If the infected nodes 0
(5)	Response the defense mechanism;
(6)	Calculate the optimal state trajectory in equation (4);
(7)	Calculate the optimal strategies in equation (21);
(8)	Analyze the influence of parameters on the optimal strategies;
(9)	Else
(10)	t = t + 1;
(11)	End if
(12)	Update and store it;
(13)	End for;
(14)	Return .
